It sounds like you are needing the Easy Grease Trailer Idler Hub Assembly # AKIHUB-545-35-EZ-K. This hub has an inner bearing with 1.378" (35mm) inner diameter, outer bearing with 1.063" (27mm) inner diameter and the bolt pattern is 5 on 4-1/2" (114.3mm). Please double check your outer bearing as the only picture I received shows the inner bearing diameter.
